Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 43818, here are decompositions:

17 + 43801 = 43818
29 + 43789 = 43818
31 + 43787 = 43818
37 + 43781 = 43818
41 + 43777 = 43818
59 + 43759 = 43818
97 + 43721 = 43818
101 + 43717 = 43818

Showing the first eight; more decompositions exist.
